Composition for artificial stone



CUAIING UH tLAS I IU.

AZAFM To all whom it may concern.-

Be it known that LJOIIN LORENZ, of the city and county of Muskegon, in the State of Michigan, have im'ented a new and useful Composition Forming an Artificial Stone to be i used in the construction of walls, paving, and all other purposes in which an artificial stone I i is applicable. ,1 The nature of my invention consists in a 5., to proper combination of ashes and cinders or MR elinkers with ordinary cement to form a perfect and durable artificial stone for the pur-' pose above specified. A material has been used for these purposes composed of clear ashes and cement, and w f cement, as well asthese materials combined Wu 1339 or adheslve substances; but so far as my me but myself {ax/m: has yet used the compound formed of ashes m ma/'20 and cinders with cement.

Experience has shown that artificial stone g made of ashes and cement is susceptible to the I action .of the elements to such a degree as to cause it to soften, scale, crack, and easily wear out; and, further, artificial stone made from cinders and cement has been found to be too gritty for many of the purposes hereinbefore set forth, is liable to become rough by use, and

. requires a very largcamonut Q1 cement in its ;0 formation, and consequently is more expensive than stone constructed by a combination of ashes with cinders and cement. 13y experiment I have demonstrated that this combination produces a stone which will not be in- 3 5 juriously affected by heat, water, or frost, and is therefore free from cracking, crumbling, sea-ling, or softening, and can be dressed and polished to such an extent as may be required.

PATENT COMPOSITION FOR ARTIFICIAL STONE, 80C.

SPECIFICATION forming part of Letters Patent No. 366,012, dated July 5, 1887,

Application filed January 3. IP87. Serial No. 223,317. (No specimens.) v

and use my invention, I will proceed to describe its construction.

I take warts of ashes and mix therewith one .art of con on then add thereto ilmmpm'ts om clinkers. If a very fine s one 18 esire crus 1 e clndcrs beforemix- 5 ing; but for the purpose df'arching,walling, paving, &c., it will not be necessary to crush the cinders. A hard and almost impervious stone will be thus formed, which can be polished, if desired. These proportions may be slightly varied, and substantial] y the same durability, hardness, and imperviousness can be obtained by increasing the amount of ashes and cinders without increasing the amount of cement-as, for instance, using fifteen or more parts of ashes and einders to one part of com' ent.

I am aware of the patents to Bald win, J ones and Gibbs, bearing date February 12, 1867, and that of B. Lande, June 3, 1884, and hereby (3o disclaim as being my invention the composition for making artificial stone described in cit-her of said patents.

Having thus described my invention, I elai m as new, and desire to seen re by Letters Patent, the following:

As an improvement in artificial stone, the compound formed from a mixture of five parls ashes, four parts einders, and one part cement, united in the manner substantially as hereinbefore set forth.
